Hi hi. :) There are a few ways to accomplish this. If you want the statblock to be truly in the middle of the paragraph (with some text flowing over it as well as under it) then I think the most straightforward way to do it is to put your intro paragraph above the `aside`, then put the rest below. Applying `float: right` to the `aside` is enough to do what you want after that.
I also cleaned up a few other parts of your code. As you start to make more complex designs it's going to be more and more important that you try to keep your indentation and tag placement consistent. I also recommend you try to put as much of your styling rules in your CSS as you can, so I moved the statblock table's styling over there.
Hope it helps. <3
